Free Flooring Calculator

Calculate how many boxes of flooring a room needs, with waste and cost.

Room area is length times width, increased by the waste percentage. That area is divided by the coverage per box and rounded up to whole boxes, and the calculator shows the coverage you end up with.

How to use the Flooring Calculator

  1. Enter the measurements of the area you are working on.
  2. Read the amount of material needed, including a waste allowance where relevant.
  3. Round up when you buy, and check the figures with your supplier.

About the Flooring Calculator

Calculate how many boxes of flooring a room needs, with waste and cost.

Home and building jobs are easier to price when you know how much material you really need. A quick estimate also helps you avoid buying too little or too much.

Tips for better results

Enter coverage per box in the same unit system as the room. Keep an unopened box or two for future repairs, since dye lots change.

Add 5 to 10 percent for waste, cuts and mistakes.

Measure twice, order once, and check quantities with your supplier.

Frequently asked questions

Why does it round up to full boxes?

Flooring is sold by the box, so you must buy whole boxes. The calculator shows the total coverage you will actually have.

What waste allowance suits flooring?

About 10 percent covers straight lay cuts. Diagonal or herringbone layouts often need 15 percent or more.

Is the flooring calculator free?

Yes. It is free to use with no signup, no watermark and no usage limits.

Is my data private?

Yes. Your inputs are processed in your browser and saved only in its local storage. They are not uploaded to our servers.

Does it work on mobile?

Yes. Zapxa works on phones, tablets and desktops. Use the print button or download a PDF to keep a copy.
